Yes, a steam blanket is one of the options.
But I think the nitrogen blanket would be more cost effective than the steam blanket.
The reason:
For steam blanket, I am thinking to purge steam from the bottom. Even so, to make the steam blanketing to be effective - to prevent air leak from outside...
The water is deoxygenated.
I found some vendors for these balls.
The material used for the balls are usually HDPE, PP or PVDF depending on the temperature and application.
I have been using the process simulators (Aspen Plus, Pro-II, HYSYS) for a long time, and I would like to give some comments from my experiences.
First, I think CJKruger gave a pretty clear and accurate guide hot to get the result from Aspen.
Here are my comments:
- H2 / Benzene compositon...
I don't think pouring oil will work. Because the oil will dissolve into water even very small amount, and that is not acceptable to boiler feed water.
Having balls floated on the water surface will definitely reduce surface area of air-water contact and thus reduce the oxygen dissolving rate...
Thanks for your posting TBP,
Can you explain a little bit more?
Do you know how the performance was - reduction of dissolved oxygen or reduced corrosion?
How much layers did they used?

I am currently doing a study for an economical way to blanket a 5,000 M3 Boiler Feed Water tank. The tank doesn't have a blanketing system at the moment, and is atmospheric tank breathing to air. Therefore the plant experiences corrosion problems caused by the dissolved Oxygen in the water which...
